MiSTer FPGA Forum

My MiSTer has 2 sticks of RAM connected. Is there anywhere in the system I can go to confirm 2 sticks RAM are connected/seen by the MiSTer/Linux?
Thanks

I’m not aware of any (and it almost certainly will not be visible on the Linux side), but I have an unconfirmed suspicion that the PSX core is auto detecting the 2nd SDRAM and using it if available, and you can see which type of memory it is using in the core options menu. Maybe someone who can read VHDL can confirm but the regular core seems to be using the 2nd SDRAM without need for the separate Dual SDRAM core. Please take all this with a grain of salt ofc …

Best way to confirm is to load a dual ram core (Jaguar or Saturn- make sure it is labeled DUALRAM). If you can boot a game in those, then you have dual ram .
